A study of fox rabies in randomly selected 15 locations in southern Germany found that the mean number of cases of rabies in each location was 4.75 with a standard deviation of 2.82. In northern Germany, a second sample of 10 locations found that the mean number of cases was 3.93 with a standard deviation of 1.4. Does this information indicate that there is a difference in the mean number of cases of fox rabies between the two regions?
